Export: Append \n to EOF is not already present

I'd rather we just got the whitespace correct :). See #117.

I think we still could use this -- note that % signs at the end of each file below:

    export: Improve design and test coverage of export

    This commit:

    - Moves responsibility for I/O back into `honcho.command` rather than
      `honcho.export`.
    - Changes exporters so that `#export()` takes a list of
      `honcho.environ.ProcessParams` objects and optional template context.
      This means that concurrency, process naming, and port assignment is
      now much more likely to be consistent between `honcho start` and
      `honcho export`.
    - Improves test coverage of the `honcho.export` package.
    - Removes a couple more fragile export integration tests.

[marca@marca-mac2 export_test]$ cat out/export_test-ansvc.conf

[marca@marca-mac2 export_test]$ cat out/export_test.conf
pre-start script

bash << "EOF"
  mkdir -p /var/log/export_test
  chown -R export_test /var/log/export_test
EOF

end script

start on (started network-interface
          or started network-manager
          or started networking)

stop on (stopping network-interface
         or stopping network-manager
         or stopping networking)%

Though this will conflict with #119, so maybe I should send you a PR for that branch...
